GREENVILLE, N.C. (AP) — Mitt Romney's presidential campaign is launching an aggressive Republican response at the site of the Democratic National Convention. The goal: stealing attention and driving new questions about President Barack Obama's leadership on the eve of his nomination for a second term.

As thousands of Democratic activists gather in Charlotte on Monday, Republican vice presidential nominee Paul Ryan will campaign 230 miles to the east in Greenville. Aides say that the Wisconsin congressman will focus on a simple question the campaign is driving this week: "Are you better off than you were four years ago?"

Romney, meanwhile, will spend much of the week in New Hampshire and Vermont preparing for three fall debates with Obama, the first scheduled for Oct. 3.
